Hi,

I live in a confined space where excessive noise will not be tollerated
by neigbours. I need a tool to grind mosaic tiles.

My current considerations a
OPTION 1
Foredom 1/3 flex shaft tool with all the diamond bits. Around $400

OPTION 2
Ingersoll Rand mini die grinder PLUS dentist/laboratory type "quiet"
compressor. I found a shop that sells a second hand "rotary vane" quite
compressor delivering 4CFM @ 10 bar with only 62 dBa noise ! Total
outlay around $1000 (new it would be around $2000). ouch.

I would prefer the Foredom as the outlay will be significantly less.
However will it drive my neigbours mad? Does the sound travel through
walls like my 1HP 4 1/2" Bosch angel grinder?

Thanks for your thoughts

Guido
